Description

Knee protector {KNEE PROTECTOR}

The present invention relates to a knee protector, and more particularly to a knee protector including a fastening dial.

A knee protector protects the joint by appropriately compressing the patella of the knee. Most of the knee guards fix the entire circumference of the knee with elasticity, which is disclosed in Korean Patent Registration No. 20-0216129 (December 28, 2000).

The knee protector disclosed in the above registration design is formed of a stretchable cloth and has a shape wrapped around the knee. The knee protector includes a far-infrared radiation pad for emitting a far-infrared ray at a predetermined position between inner and outer surfaces. When the wearer is worn on a user's knee, blood is circulated by far-infrared rays radiated from the far- So as to alleviate the pain of the joint.

However, the knee protector disclosed in the above-mentioned registration design can not effectively press the periphery of the kneecap to protect the knee joints when the knee is simply moved while pressing the periphery of the knee, which is insufficient for relieving the pain of the knee. The blood circulation by the far-infrared rays is not promoted smoothly.

Commercially available knee guards are sold or introduced on the market with various types and functions to protect the knee joints with leisure or medical aids such as sports, sports, mountaineering, etc.

Such conventional knee protection is disclosed in Korean Patent Publication No. 10-2007-0075091 (2007.07.18), Korean Registration No. 20-0336506 (2003.12.08), Korean Registration Practice No. 20-0353935 (June 2004) And Korean Registration Practice No. 20-0441877 (2008.09.08), etc.

In the above conventional techniques, a pair of Velcro tapes are commonly arranged in one direction, and a Velcro tape is adhered in the opposite direction so that the joint protector can be worn

Therefore, when the velcro tape is stretched in a state in which the stretchable knee protector is stretched to some extent, the joint protector contracts and presses the knee. In this case, the elasticity of the knee protector is set to a certain limit. In order to increase the pressing force of the knee, There is a limit to extending the protector.

That is, although the above-described conventional techniques allow the Velcro tape to support two points in the same direction to enhance the binding of the knee protector, the degree of pressing by the knee protector becomes equal to the degree of pressing at one point where the Velcro tape is adhered, There is a problem in increasing the pressing force by the protector.

In addition, the above-described conventional techniques simply wear the Velcro tape arranged in the same direction on the knee in such a manner that the Velcro tape is simply attached to the velcro fabric. Therefore, when the knee protector is operated for a long period of time or climbing, If the knee protector is loosened, the reliability of the product is lowered due to the inconvenience of wearing the knee protector again.

Furthermore, the knee protector does not take into consideration the size of the user's body. Therefore, the pressing force is applied by adjusting the adhesive portion of the Velcro tape. In this case, the adhesive area of the Velcro tape is reduced and the knee protector is loosened.
